I've got a stone chipped drive and I think a local cat must be mistaking it for a kitty litter. For the last few days, cat dumps keep appearing just outside the front door (ready to be stepped on), or appearing on the lawn.

I have not actually seen seen the cat, but judging by the size of the dump I would say it's definatley feline. Any tips to stop the bugger desecrating my property?

Anything with citrus. Tesco do an All purpose Cleaner called Daisy and it is citrus scented. Mix a strong dose and spray it all over the drive.
Your drive way will smell devine and hopefully keep the cats away.
